Since coming back from Penang, little boy has suddenly decided that he had enough of lying down, and has been crawling around the house super fast. At times he gets over-ambitious and even tries to stand on his own. So... he has been knocking his head on the ground a few times each day, and has a blue-black bengkak on his forehead to show. He is now super-energetic and not easy to keep up with.
Anybody out there got some good advice?
